Will this fit my Milwaukee M18 drill?

Yes. It uses the M18 slide-on footprint and works with Milwaukee 18V tools and chargers that take that pack. It does not fit M12 or M4 tools.

How does 4.0Ah compare with other M18 packs?

It runs longer than a 2.0Ah compact pack and shorter than a 5.0Ah or 6.0Ah high-capacity pack. It is also lighter than the high-capacity packs, which helps on tools you hold overhead.

Is it as good as a genuine Milwaukee battery?

Genuine Milwaukee packs typically use better-matched cells and last more charge cycles. This pack is a lower-cost alternative that suits light and occasional use better than daily professional work.

Does it have a charge indicator?

No. The pack has no fuel gauge, so you check charge by putting it in a tool or charger.

Our take on the Banshee V20 20 Volt Max 4.0AH Lithium-Ion Battery

The Banshee V20 is a 20V Max lithium-ion battery pack rated at 4.0Ah, sold as a replacement for Milwaukee M18-style tools and chargers. It uses the same slide-on M18 footprint, so it fits Milwaukee 18V drills, impact drivers, saws and lights that take that pack. A 4.0Ah pack sits in the middle of the range: more runtime than the compact 2.0Ah packs, less than the high-capacity 5.0Ah and 6.0Ah options, and lighter than those. Third-party packs like this one trade Milwaukee's cell quality and warranty support for a lower outlay, and owners of such packs commonly report shorter long-term life than genuine batteries.
